SHOT-DRILL EXPERIMENTS. 



7thly. The men employed for these experiments 

 were fed exclusively upon vegetable diet, and they 

 consequently secreted a considerably smaller amount 

 of nitrogen than the flesh-eaters engaged in the 

 tread wheel work. The other conditions were, how- 

 ever, equally unfavourable for showing the excess 

 of work performed, over the amount derivable from 

 muscle metamorphosis. 



In shot-drill, each man lifts a 32-lb. shot from a 

 tressel to his breast, a height of 3 feet ; he then 

 carries it a distance of 9 feet, and lays it down on a 

 similar support, returning unloaded. Six of these 

 double journeys occupy one minute. The men 

 were daily engaged with 



Shot drill .... 3 hours.

The total average daily external work was esti- 

 mated by Haughton at 96,316 metrekilograms per 

 man. 



The following is a condensed summary of the 

 results of these experiments :
